Question about Samsonite Spectrolite 2.0

On the manufacturer's website https://www.samsonite.in/spectrolit... I only found the following dimensions W 430 x H 310 x D 180 mm. These 18 cm should also be expandable to 22 cm, according to the linked page. This also explains the original specifications. I have just taken care of the correction and thank you very much for your advice. Please note that the bag is intended for notebooks up to size 15.6".
